Powering up: LLNL prepares for exascale with massive energy and water upgrade

To prepare for the exascale El Capitan and the next generation of power-hungry supercomputers, construction crews and maintenance workers at LLNL have been hard at work since late 2019 and throughout the COVID-19 pandemic on a massive, $100 million Exascale Computing Facility Modernization project. The project will nearly double the energy capacity of the Lab’s Computing Center, eventually supplying the facility with enough wattage for about 75,000 modest-sized homes.

Updated exascale system for earth simulations

A new version of the Energy Exascale Earth System Model (E3SM) is two times faster than its earlier version released in 2018. E3SM2 was released to the broader scientific community in September. The project is supported by the DOE's Office of Science in the Biological and Environmental Research Office.
